IPv6 slaac support

[kroon040]

Hi,

I see the ipv6 DHCP support is enabled. I got ipv6 working from my provider and it is working using ipv6 with Slaac for getting ipv6 adresses. Is the an option to support it with ems-esp32? the esp-idf support it but is not default enabled

This project, like most ESP8266/ESP32 projects, uses the Arduino core (https://github.com/espressif/arduino-esp32) and not built using the native ESP-IDF (which is something I've been considering). Unfortunately, the package comes with a pre-built SDK that's built without the CONFIG_LWIP_IPV6_AUTOCONFIG parameter set to enable SLAAC. The only way around this is to build a custom lwip library. It's not hard to do and add to platformio. I even think Tasmota or esphome may do something similar. Worth investigating if you have time. I'm pretty busy these days :-)

this should be possible now with #473
